<p>I'm taking AP Bio right now and I plan to take the SAT II and AP exam for it. I got the Bio Cliffs book and Princeton review. How should I go about studying from both of them? </p>

<p>Should I learn about one topic in Cliffs and another topic in PR at the same time? or what? :o</p>

<p>Pretty much. I don't think they will differ than much. I'm studying for both AP and SAT II U.S. History using like 5 books...so yeah...</p>
